Il lustrated below, with brief descriptions, are a number of projects IHC Marine and Mineral Projects

have completed in recent times.

De Beers Marine Subsea Excavation Tool and Topside Equipment

Market: Subsea Diamond Mining Year: 2005

This project entailed the design, manufacture, installation and commissioning of several major

systems for the flagship diamond mining vessel, mv Peace in Africa – recently renamed mv Mafuto. This included the subsea crawler, launch and recovery and four point mooring systems.

Crawler The mining crawler was the primary mining element of this project with the function of providing a

mobile dredging tool to deliver product to a surface processing plant. The major functional areas of the design were: tracks, a pivoting boom assembly, a suction system consisting of a variable speed

2432 kilowatt (kW) motor coupled to a dredge pump, thrusters to control tool orientation during launch and recovery, a hydraulic system powered by a HPU comprising a 500 kW motor and pumps,

electronic system with an array of sensor equipment and the tool lubrication system.

LARS

The crawler weighs in excess of 240 tonnes. This requires a massive launch and recovery system (LARS) capable of reliable operation during unfavourable offshore conditions. The winch for this

system is powered by nine 185kW motors, providing a total of 1665kW of power for operational depths up to 200 metres (m).

Mooring

To ensure that the vessel remains in position above the crawler during mining, a four-point mooring

system was necessary. The system consists of four 100Te line pull mooring winches, four fairleaders, bend sheaves and line tension meters. The mooring and LARS equipment were classed/certified

according to the Lloyds Register of Shipping.

De Beers Marine mv Coral Sea Mooring Winch

Market: Subsea Diamond Mining Year: 2007

This project entailed the design, manufacture, installation and commissioning of the starboard aft

mooring winch, tower assembly, deck bend sheave and fairleader on the mv Coral Sea vessel. Control and instrumentation was also a part of the scope. The winch stores 1900m of wire rope and

weighs over 47 tonnes; it is powered by three hydraulic motors.

As part of an overall l ife extension project on the mooring system, IHC MMP is currently managing the fabrication of a replacement for the port aft mooring winch and aforementioned ancil lary structures.

Subsea 7 Multi-Reel Drive System

Market: Oil and Gas (Flexible Product Handling)

Year: 2007

This project entailed the design, manufacture, installation and commissioning of an innovative multi-reel drive system for flexible pipelay in the oil and gas industry. This particular installation was on the

main deck of the Solstad Multi-purpose Support Vessel, mv Normand Seven. The reel drive system can accommodate a variety of standard product reels – up to 150mm in diameter, with a maximum

weight capacity of 250Te.

Subsea 7 Air Dive Handling

Market: Oil and Gas (Air Dive Support) Year: 2007

This project entailed the design, manufacture, installation and commissioning an air dive handling

system for the purpose of delivering support to divers and ancillary equipment to 50m water depths. The system, which was classed/certified according to the Lloyds Register of Shipping, included:

• A diver hoop boom system for launch and recovery of a diver’s hoop to prevent divers from being pulled towards the thrusters of the vessel;

• A dive basket deployment system with associated clump weights for dive basket guidance

and emergency recovery;

• A triple drum winch system for product (air, hydraulics and welding cable) storage, deployment and recovery; and

• Skid mounted luffing a-frame LARS system with constant tension winches.

Div er Hoop Boom The Diver Hoop Boom System is a non man-riding l i fting appliance, the primary function of which is

to launch and recover a Diver Hoop to a maximum water depth of 50 metres below the water surface. The Hoop Boom Beam can be extended, via a rack arrangement driven by the pinion drives, to a

maximum of 20 metres beyond the vessels side. The Hoop Boom Beam can be extended to the port side or to the starboard side of the vessel.

Operationally, a Diver Hoop is attached to rigging from a Main Lift Winch, the Diver Hoop is raised out

of its support frame and the Hoop Boom beam is extended to a safe distance from the vessel side. The Diver Hoop is then lowered to just below water surface. The Hoop Boom Beam is then extended

to the predetermined distance from the vessels side, whilst control of the winch keeps the Diver Hoop just below the water surface. Once the Hoop Boom Beam is extended fully to the predetermined

distance from the vessel side, the Diver Hoop is lowered to the predetermined operating dive depth.

Photo of Diver Hoop Boom Extended to Port

A Secondary Lift Wire is lowered to the diver hoop and a hook at the end of the wire of the Secondary Winch is then attached to the strop wire on the Diver Hoop. This serves as a secondary means of

recovery in the event that the main lift wire fails to recover the diver hoop. The recovery of the Diver Hoop back on board the vessel is done in reverse order to the launch.

Air divers are lowered into the water to the required working depth via a Dive Basket Deployment

System. The divers swim from the dive baskets to the Diver Hoop via an established swim line. The divers attached themselves, via clip locks attached to the air umbilicals, to predetermined swim lines

attached to the Diver Hoop. The length of umbilical attached to the swim lines are predetermined to ensure that, in the event of an accident or diver(s) becoming incapacitated, the diver(s) cannot be

drawn into the vessel propulsion units.

Div e Basket Deployment

The Dive Basket Deployment System is a man-riding lifting appliance, the primary function of which is to deploy two divers and their equipment to a predetermined operating depth, up to a maximum of

50m below the surface. Each Dive Basket Deployment System consists of two Dive Basket Winches and two Clump Weight Winches.

Operationally the Dive Baskets are deployed in the following manner: the forward and aft Dive

Baskets and Clump Weights are both raised to clear deck recess and the T-bar is extended via hydraulic cylinders, whilst controlling the four winches, to a maximum of 1.7 metres away from the

side of the vessel. One Clump Weight is then lowered to a predetermined operating depth below the water surface. The Dive Basket is lowered to a deck where the divers can enter with all the necessary

equipment. Once safe to do so, the T-bar is extended out from the vessel side and the Dive Baskets are lowered operational depth, coming to rest on or just above the Clump Weights. The divers then

swim from the Dive Baskets to the Diver Hoop. Recovery of the Dive Baskets is carried out in the reverse order to the launch.

The primary function of the Clump Weights and wires are to act as a guide for the deployment of the

Dive Baskets and reduce drifting below the surface. However, the Clump Weights also act as a secondary means of recovery of the Dive Baskets in the event of a primary l ift failure.

Triple Drum Winch System

The Triple Drum Winch System is a non man-riding l i fting appliance consisting of three independently driven and controlled storage drums mounted to a base frame structure. Each drum is

dedicated for a Gas Burning Rig hose bundle, single Air hose and Hydraulic hose bundle, respectively. The hoses are diverted of the vessel side by three independent ‘Banana Sheaves”

designed to be mounted to the underside and outboard side of the vessel deck.

Constant Tension Winches and Luffing A-Frame

The Constant Tension Winch System is a non man- riding lifting appliance consisting of a luffing A-frame and two Constant Winches mounted to a base frame. The A-Frame can be luffed, in-board and

out-board, to a maximum of 2m from the vessels side. Constant Tension Winches are mounted on the inboard side of the base frame.

The Constant Tension Winches have two modes of functionality and are independently selectable for

normal winch mode or constant tension, (render) mode. The primary function of the Constant Tension Winch System is to deploy work baskets with equipment, tools or gas burning, air or hydraulic hoses

from the Triple Drum Winch Systems.

Operationally one winch is selected to perform the Constant Tension Mode. The wire rope is fed through the sheave blocks mounted to the A-frame cross member. The end of the wire rope is

attached to the work site, (for example; an offshore platform structure below surface). This wire once attached, is now in constant tension and the winch function automatically heaves in and out to counter

the vessels motions. The wire rope from the second winch, in normal winch mode, is attached to a travell ing block to which either a work basket or hoses are attached. The travell ing block and its load

are then transported along the constant tension wire to the work site.

Subsea 7 Reel Drives

Market:Oil and Gas (Flexible Product Handling) Year: 2008 This project entailed the design, manufacture, supply and delivery of two mobile flexible product reel

handling Reel Drive Systems (SFL and ESFL) to deploy steel flying leads and electrical steel flying leads. The equipment was classed/certified according to the Lloyds Register of Shipping. All

necessary ancil lary equipment was also supplied by IHC MMP.

Mertech Bow Roller

Market: Submarine Cable Recovery Year: 2010

Mertech Marine had an existing cable recovery guide roller assembly on the bow of the mv Lida. The

unit, however, was not effective as it has encountered problems during cable recovery. The design of an alternative solution was requested of IHC MMP. The proposed solution – which was subsequently

fabricated and installed – consisted of a powered bow roller and support structure to assist with the recovery of cable, taking into consideration the minimum bend radius of the cable, through a

magnitude of recovery angles.

De Beers Marine Sampling Tool and LARS Modifications

Market: Offshore mining and Exploration

Year: 2009

De Beers Marine (DBM) procured a Launch and Recovery System (LARS) for the new subsea sampling and ground truthing tool from New Zealand Diving and Salvage. The LARS was designed to

be installed athwart-ships onto a charter vessel but was never commissioned due to various technical problems being experienced with the sampling tool. DBM contracted MMP to assist with a review of

the existing LARS design, design the required modifications and produce detailed drawings for the modifications to be implemented in New Zealand prior to fitting the LARS to the proposed charter

vessel.

Excavator Trailing Cable Reelers

Marker: Open-pit Mining

Year: 2013 - 2014

The excavator trailing cable reeler is designed to handle and store the supply cable providing electrical power to large open-cast mining excavators, such as the Hitachi EX3600. The cable reeler safeguards

the power cable extending from beneath the excavator by maintaining a constant tension thereupon. This eliminates the risk of the cable becoming tangled, being driven over by the excavator and of the

excavator travell ing beyond the limits of the length of cable which is wound on the reeler drum. The cable reeler is designed to be permanently cantilever-mounted to the structure between the tracks of the excavator. Most recently IHC MMP manufactured four units for Turkuaz Machinery who will be

attaching them to the aforementioned Hitachi excavators to be supplied to a mining operation in Eastern Europe. IHC MMP also provided installation supervision and commissioning services on-site.

Another four units are scheduled for delivery to the same client over the next two years.

IHC EB Cursor Winch

Marker: Offshore

Year: 2013

The Cursor Winch – designed and manufactured for IHC Engineering Business – is located on the stabil iser unit of a marine launch and recovery system. The system is employed to recover a remotely

operated underwater vehicle and was designed to Lloyds Register of Shipping specifications. Unusual spatial constraints imposed by the physical design of the stabil iser unit, along with a specified safe

working load of 20 tonnes, required IHC MMP to develop an innovative design for the winch.

IHC SWORD Seafloor Sampling Tool

Market: Deep-sea Mining and Exploration Year: 2012

Mining operations are by their nature founded on the existence and understanding of the mineral resources. Exploration, identification and development of mineral resources are fundamental to the

existence of any mine. Whilst subsea geophysical data acquisition methods have improved hugely over the past few years, subsea geotechnical data acquisition (specifically sampling) has not seen the

same level of advancement.

SWORD The project entailed a background study, concept and high-level design of a new generation seafloor

sampling tool for core sampling. The Sonic Wireline-Operated Remote Dril l (SWORD) is the solution developed by IHC MMP. The IHC SWORD is capable of providing class A samples (4 inch), up to 50m

ground penetration, fully cased, at a depth of 2000m. The SWORD and associated LARS is completely modular, capable of fitting into standard offshore containers, for quick mobilization and

demobilization. The detail design and subsequent pilot fabrication projects are imminent.

Containerised Winch

The positive reception of the SWORD lead to a secondary project entailing the investigation of winch

containerisation. Increasing the modularity of the system will enable swift deployment and improve redeployment turn-around times in case the client were to require the SWORD to transfer between

multiple vessels.
