In offshore painting jobs, your responsibilities include blasting, painting and various construction duties aboard offshore rigs and facilities. As a blaster, you check equipment, install dust barriers, prepare the blasting site, and operate machinery to sandblast appropriate surfaces. The blaster coordinates and communicates with the offshore painter to complete the job. As a painter, you also assist with the preparation but operate equipment to spray paint and apply protective coatings. Offshore painting projects focus on offshore gas and oil rigs and are essential to maintaining and preserving surfaces and machinery.
