Characteristics

Barge shipment - Characteristic

Barge – commonly flat top barge (a.k.a dumb barge).

Non self propelled. Prime Mover is the tug. Both tug and barge connected by a towline. Slow moving, demands good manoeuvring skills.

Economical mode of transport. Lower cost compared to conventional vessels.

Able to access port with shallow draft, e.g ports along rivers, jetties located within shallow estuaries etc

Barge shipment - Characteristic

Types of tow arrangement

Single Tow: The most frequent/common arrangement.

1 tug pulling (towing) one tow

Typical arrangement; towline of tug connected to bow of the barge.

Towline from tug connected to Smit towing brackets on barge using delta plate,

chaffing chain, shackles etc.

Types of tow arrangement

Tandem Tugs : 2 tugs pulling (towing) one tow

Normal arrangement for ocean tow with large objects/barge

Typical arrangement; tow wire of lead tug connected to bow of the 2nd tug and

2nd tug line connected to towed unit

Usually larger of 2 tugs is positioned between lead tug and tow.

Barge shipment - Characteristic

Types of tow arrangements

Breasted Tugs: 2 tugs pulling (towing) one tow

Both tugs positioned next to each other and in front of the towed unit

Usually used for towing problematic structures where speed is not important

BUT maintaining towing control is.

Types of tow arrangements

Double Tow / Tandem Tow (a.k.a “Double Trouble”): 1 tug pulling (towing) 2 tows

Highest risk compared to other types of tows

Customarily 2 ways to secure the tows - Tow line is secured to the 1st towed unit. Another tow line passes the 1st unit

and secured to the 2nd unit.

- Tow lines from the tug is secured to the 1st towed unit and another intermediate tow line secured to between the 2nd towed unit and the 1st towed unit

Barge shipment - Characteristic

Double Tow – two towed units connected to different towing equipment on tug.

Barge shipment - Characteristic

Tandem Tow – two or more towed units connected in series i.e tow line connected behind 1st unit to the front of 2nd unit.

Barge shipment - characteristic

Why double trouble? In an emergency, tug is required to recover 2 tows.

Very difficult to manoeuvre

Often, no crew on 2nd tow (or even on 1st tow) – tug would not have any idea on

the condition of the 2nd tow.

In the event of issues with tow, especially 2nd tow, tug would most likely not be aware

In congested waters or water in very close proximity to underwater obstructions, the service of additional tug is often required (but not often arranged).

Barge shipment – Underwriting

Typical profile of tug and barge in the region: Unclassed or classed with non IACS

Underpowered

Questionable condition

Workhorses, little or no maintenance

Low morale crew with little or no motivation to ensure safety of cargo

Not usually subjected to PSC inspections

Barge shipment - Underwriting Information critical to underwriting process

Type of tow Tug and barge specifications (size, capacities) Tug and barge flag and class Age Tug horsepower / bollard pull Cargo details (type, weights, sizes, special requirements, protection) Load and discharge port (location, facilities, risks)

Barge shipment - Underwriting Information critical to underwriting process

Voyage distance and routes Expected weather and sea conditions Owners/operators reputation or record Other expected risk – cargo specific, piracy/hijacking etc

Barge shipment – Reality Check In reality, typical information that is provided (often at short notice)

Tug and barge name (or at times only tug or barge name – sometimes with wrong spelling!)

If lucky, with registry certificates and if very lucky with Class Cert

Cargo name and value (sometime very general description e.g machineries) General load and discharge port names (e.g Port Klang, South Kalimantan)

“Reply urgently as vessel about to complete loading and will depart soon”

or worst

“vessels have departed”

Above is recipe for disaster

Barge shipment - characteristic

Prudent underwriting

Ensure all relevant information is obtained

Refer to your internal Marine Risk Management team if you have one and/or

Consider engaging a reputable and qualified surveyor.

Towage Surveys – Surveyor Selection

Is objective, fair and able to provide honest and impartial recommendations.

Towage Surveys – Surveyors

Expectations from surveyors – among them:

Surveyor to be from third and impartial independent party who has absolutely

no interest in the venture.

Surveyor must inspect the tug and tow(s) and see that all necessary preparation has been carried out.

Surveyor expected to base his/her opinions and recommendations on what is required based on past experience, practical knowledge, local and statutory requirements to ensure safe and successful completion of the venture.
