Removable gangway for J-class vessels Jumbo

Jumbo uses J-class vessels that have to sail without hatches on several occasions. When this is the case, the crew cannot walk uninterruptedly over the coaming because of the two cranes. TWD was requested by Jumbo to design a gangway to walk around the crane on top deck level, at the port side of the crane. The gangway is removable, can replace the hatches at the J-class vessels, and can be used for future projects.
