Abstract
A drilling or other offshore application vessel which can have the outward appearance and other characteristic of a monohull vessel, comprised of two or more sub-hulls each of which may be sailed as an independent ship through restrictive waterways which would prevent passage of the assembled vessel. The sub-hulls are later joined together to form a composite drilling or other offshore application vessel. The sub-hulls in one example include a recessed portion which reduces the amount of ballast needed to balance the sub-hulls.
