Brazilian offshore services group and yard Belov Engenharia Ltda has decided to build and operate two new dive support vessels (DSVs).
They will be built by Belov’s own fabrication yard in Salvador in Brazil and are being built in expectation that demand in Brazil’s offshore oil and gas sector will increase in coming years. They will be under 500gt, of 41m length, 10.75m breadth and have a speed of 12 knots. Crew will be 38 including divers. Belov has commissioned marine architects Robert Allan Ltd to prepare the contract design package of the vessel. They will be named Belov Humaita and Belov Amarlina and will be of type RAlly 4000, fitted with a dynamic positioning system (DP2). They will have a diesel-electric propulsion plant driving water jet propulsors and bow thrusters. They are being designed to be fitted with a launch and recovery system for remotely operated vessels, and will have an aft mounted A-Frame to operate the diving bell, a decompression chamber to support the divers and extensive crew quarters.
