Article by Workboat World, published January 2018:


 It was only last month that we reviewed Doria, the 54-metre OPV that was a result of a multinational collaboration spanning three continents.

 Delivered to Kenya late in 2017, Doria is a massive upgrade for the Kenyan government in terms of both technology and capabilities and it is for these reasons that Doria and her builder Western Marine Shipyard has been awarded Best Large Patrol Boat.

 A hybrid "combined-diesel-and-diesel" propulsion system that incorporates twin propellers and a centerline waterjet is normally only seen on military vessels in wealthy nations due to the complexity of such an arrangement. For Western Marine to have undertaken such an installation is a credit to their abilities as a Ship builder.

 Western Marine won the contract to build Doria after the owners carried out a thorough due diligence on the company and an investigation into their track record. Yard visits and meetings with key technical personnel were also key to winning the contract and impressing the owners as was the ability to construct a complex vessel for such a competitive price.

 Western Marine has seen an overall uptick in business since the end of 2016 thanks to a policy of taking contracts for which margins were only minimal and sufficient to cover costs and keep the company afloat.

 Future projects include a recently signed contract for a high-end purse seiner for a Norwegian client and a landing craft for a UAE client. The Chittagong Port Authority has signed a contract for a 25-tonnc bollard pull tug whilst the Payra Port Authority has signed for a 60-tonne bollard pull tug.

 Western Marine sees a demand for more offshore patrol craft and is confident that it will be able to use its experience with Doria as a springboard to future contracts.
