These include a 1,400m³ LPG tanker vessel, built by Saigon Shipbuilding & Marine Industries One Member (Saigon Shipmarin) for operation on the Mekong River. The Ho Chi Min City yard, which undertakes both newbuild and repair work, is part of the Vietnamese government-controlled SBIC (Shipbuilding Industry Corporation).

A pair of Cummins 855 diesels delivering 400bhp each provides propulsion power, with two Cummins 6C engines powering 120 kW generator sets.

The 60m long, 11m beam LPG carrier has two gas tanks, and is designed to 2.6m draught for shallow water operation. The ship, named Faco, is owned by the F.A. Joint Stock Company and built to the Vietnam Register Rules and National Inland Regulations, classed for near shore and river operations. It is believed that it will be the first in a class of similar ships.

Cummins power also provides the heart of a novel diesel-electric plant for a 90m tuna fishing vessel, Belle Isle, recently completed by South East Asia Shipyard, a subsidiary of the French company Piriou.

The vessel is designed to fish with a 1,200m x 270m net, anchored at one end by a 1,000bhp power skiff powered by a Cummins KTA38 engine. The ship itself houses a comprehensive array of fish processing equipment and freezers, and the power demands from these, plus the on-board net handling systems and the hotel load needed for the large crew carried, prompted the choice of a diesel-electric power plant. At the heart of this are four Cummins KTA50-DM diesels each delivering 1,240kW at 1,800rpm. This system allows a wide range of variables to both conserve fuel and/or meet maximum electrical demands including vessel speeds of 15.5-knots. The appropriate generation and distribution of power between the electric propulsion motors and onboard systems is managed by an interfaces and control system supplied by Techsol of Canada.

Australia-based Strategic Marine bas built a strong reputation for high performance crew boats. Primarily built at its Singapore yard, these have been delivered with a variety of sizes and power configurations.

Current projects include a series of 10 42m crewboats with steel hulls and aluminum superstructures for Brunei’s PTAS Marine, to an Incat Crowther design. The first two hulls and superstructures were fabricated at Strategic’s Vietnam shipyard and completed in Singapore, while the remaining eight are being built entirely in Vietnam.

Each of the LR-classed crewboats is powered by three IMO Tier II compliant Cummins main engines; a central KTA50-M2 delivering 1,800bhp at 1,900rpm, with two KTA38-M2 wing engines, each rated 1,350bhp at 1,900rpm. The total power of 4,500bhp will drive three FP propellers through Twin Disc gears, giving a speed of 20 knots at 85% MCR and 40dwt. Each vessel will have a pair of Cummins 6BT5.9 80kW gensets with an additional 425bhp Cummins QSJ11-D(M) engine to power twin bow thrusters.

Accommodation is provided for 12 crewmembers, 30 rig workers and, in the event of emergency, 100 survivors. 100m² of clear deck space will take up to 10t of cargo.
