Of particular note are their Cummins powered aluminium crew boats. In 2004 and 2005 Arabian Gulf Mechanical & Contracting took delivery from Grandweld a series of five 30.5m crew boats, each powered by a pair of Cummins KTA38 M2 engines. In the same period, Inchcape Shipping took delivery of a 33.5m crew boat powered by three Cummins KTA38 M2 engines.

More recently Grandweld has delivered two aluminium 40.1m crew boats, the ‘Express 56’ and ‘Express 57@ to Abeer Marine Services. These vessels are also powered by three KTA38 M2 engines, each generating 1,350hp at 1,950rpm and turning five bladed propellers through Twin Disc MGX6690 S gearboxes.

The boats are achieving 24 knots with a 251 ton displacement. A 7.28m beam allows them to carry up to 128 tons of cargo. A relatively shallow draft of 1.74m is maintained with the aid of a shallow recess along the aft keel line for the centre propeller.

Auxiliary power includes a Cummins 6CT8.3 for bow thruster power and two Cummins 6B-CP99D (M) powered 99kW generators. The 4,050hp vessels are registered in Panama and will be working in he Red Sea nd Arabian Gulf under charter to a Saudi company.

Established in 1984, Grandweld, a part of the GMMOS Group of companies, is located in the Dubai Ship Docking Yard at Al Jadaf that has a 5000-MT Synchrolift of 100m length capacity.
