Topside And Underwater Construction

Mooring Reviews


Our Mission is to complete each project safely, within the projected budget, and contributing to the technological advancement of our industry.

What makes us different?

Anyone can perform welding and engineering tasks on an open surface, but doing the same underwater requires superior technical understanding as well as the skill to reduce long-term risks of atmospheric-based incidents and failures. Delivery of the highest quality finished products is our priority. We understand the value of time invested in a maritime project.

Most maritime companies that offer similar services don’t have a perfect safety record; even the slightest negligence on-board can cause huge losses, that might end up risking the lives of on-site workers. Swordfish Diving LLC is passionate not only about our customers’ satisfaction but also about keeping our front-line workers, site supervisors, and engineers perfectly safe. We aim to deliver superior services with a perfect safety record. We offer complete Hard Hat Diving kits that stay within our clients’ budgets so that we can foster long-term relationships.
