From the beginning,

the oceans have been a

major factor in the evolu-

tion of mankind. We

depend on the oceans for

transport, fisheries, and

exploration to harness

subsea natural resources.

Today's maritime

structures and vessels are

strong, well designed and

technically advanced, but

the challenges and

demands associated with

their use have increased

in complexity. The need

for leading expertise in

the maritime industry is

as strong as ever..

Moss Maritimeprovides leading technology, expertise

and experience when designing and

engineering gas carriers, offshore

platforms and special purpose offshore

vessels. Moss Maritime’s engineering

staff is experienced in technical

disciplines, such as gas/cryogenics,

naval, mechanical, electrical/instru-

mentational, structural engineering,

Health, Safety, and Environmental

(HSE), and project development.

Moss Maritime is an international

pioneer in the development of gas

carriers for LNG, LPG and ethylene.

Since its introduction in 1971, the

Moss spherical containment system

has been the world’s leading seaborne

transportation system for LNG. The

new generation of large LNG carriers

with slow-speed diesel propulsion are

fitted with the patented Moss RSTM

reliquefaction system. This unique

in-house LNG expertise is used to

develop new concepts for floating

receiving terminals and production

units for LNG.

MossTM

LNG

Carriers

LNG CarriersThe MossTM LNG carrier with spherical LNG tanks represents the safest and most reliable LNG containment system on the market.The spherical tank offers simplicity in fabrication and operation, and after more than 30 years of operation, the Moss LNG tank designremains unmatched in terms of reliability and unplanned off-hire.

The simplicity of the spherical shape of the Moss LNG tank enables high accuracy for predicted stresses and fatigue life of all parts of thetank structure, thereby eliminating the need for a full secondary barrier.

Partial loading at any tank filling level is inherent in the design, making both existing and new Moss LNG carriers superior to carrierswith other containment designs, especially when handling spot trades and offshore loading/unloading. Moss LNG tanks are independ-ent from the ship’s hull and are not to the hull strength nor affected by possible damage to the ship’s hull.

Propulsion includes: slow-speed diesel engines, steam turbines, duel-fuel diesel electric or combined-cycle turbines, with single or twin screws.

• Tank volumes 147,000 – 270,000 m3

• 4-5 spherical tanks per LNG carrier

• Service speed: 19.5 – 22.0 knots

• Propulsion: Slow-speed diesel engines, steam turbines, duel-fuel diesel electric or combined-cycle gas turbines, with single or twin screw

Moss Reliquefaction SystemThe Moss Reliquefaction System is based on a closed nitrogenexpansion cycle that extracts heat from the boil-off gas:

• All cargo preserved during voyage

• Partial liquefaction and separation of non-condensable, which means reduced power demand

• Reduced liquefaction power consumption due to reduced BOR (0.085% - 0.10%/day)

Moss Containment SystemMoss LNG Tanks are the industry reference for reliable LNG transportation. They feature:

• Robust tank structure

• Unbeaten record – over 5000 tank-years with no failures or leaks

• Design not susceptible to sloshing damage: any filling level is confined in the tanks

• Design suitable for worldwide harsh environment operations

• Moss LNG carriers are designed with a considerable average distance between hull skin and cargo tanks.

• Extensive model tests have verified that a 40m diameter Moss cargo tank may suffer a 4m indent before rupturing

LNG Tank SloshingThe shape of Moss LNG tanks is designed to minimize sloshing forces and avoid filling restrictions. Moss LNG tanks are fit for:

• Large carriers

• Partial cargoes

• Floating terminals

• Offshore shuttling

• Spot trades

Increased Flexibility and EconomiesMoss LNG tanks ensure:

• No restrictions on partial filling

• Maintenance-free cargo tank and insulation system

• Easy and quick stripping

• Pressure discharge in case of pump failure

• Easy visual inspection of the insulation and the inner hull at any time

Drilling Platforms The design of the MOSS CS50 MkII is an evolution of the proven MOSS CS40/50 platformdesigns. A large deck provides generous storage areas, dedicated and protected areas for assemblyand handling BOP and X-Mas trees, plus direct access to running position in the moon pool.The design is further suited for installation of a re-injection plant and/or a cuttings handlingplant for shipment to shore and subsequent recycling. The MOSS CS50 MkII is designed toaccommodate a range of drilling platform requirements, such as:

Dual-activity drilling operationsA double derrick makes it possible to perform simultaneous operations, thus improvingdrilling efficiency by 30% compared to that of a conventional single derrick operation.

Dynamic Positioning (DP)DP, as the only means of position-keeping, reduces the down-time when moving between loca-tions and improves the efficiency when compared to an anchor-moored unit. The MOSS CS50MkII is specified with the highest DP class (IMO Class III) for maximum redundancy and safety.

Designed for harsh environment operationEquipment and systems are specified and designed to operate in low ambient temperatures, suchas those found during operation in Arctic waters. Special consideration has been made to pro-vide crews with safe and protected working areas under severe weather conditions.
