Gibraltar’s Gibdock shipyard has completed a challenging maintenance and upgrade program on the 6430bhp DP2 class ROV/Subsea Service and Platform Support vessel, Toisa Vigilant. The 2005-built, 3426dwt vessel spent over three weeks at the yard in July and August this year for a diverse package of works. For Sealion, Gibdock undertook a series of conventional docking works, including the extensive overhaul of the MAK 8L26 main engines, the two bow thrusters and two stern thrusters.
