Shadow Boat development


I am Australian, I am new to this forum and I own a small ship 36m which is currently on charter in Papua New Guinea.

I am interested to learn the pro and cons of developing my ship as a small shadow boat with the addition of a heli pad, toys, dive master, medical room, nurse and any other support mechanism that can be introduced.
The ship accommodation for up to 20 persons in 9 cabins bow thruster. CPP

2150 litres per day fuel consumption and is a go anywhere in the world ship except for ice.
