When a ship needs a Diver urgently, the quality of the team matters even more than usual. Emergency Diver services in Nagoya rely on a team that is trained, equipped and ready to work safely under pressure from time and weather.
An emergency dive team normally includes a dive supervisor, at least two working divers, a standby Diver, a surface tender and, where needed, a technician for CCTV or welding equipment. The supervisor controls the dive from the surface and has the authority to stop it. The standby Diver is dressed and ready, so that help can reach a working Diver at once.
Our emergency kit includes surface-supplied diving gear, full-face masks, communication systems, CCTV cameras and lights, hand tools, cutting and patching equipment, and a basic medical kit. Equipment is checked before each call-out. For special tasks, such as welding or cofferdam work, extra equipment is brought as the plan requires.
Surface-supplied air diving is limited in industry guidance to a maximum depth of 50 metres. Most work on ships in port is much shallower, often under 20 metres. Current, visibility, temperature and wind may all reduce the safe working time. The supervisor sets limits for each dive and records them in the log.
Every emergency has its own risks. Before the dive, the supervisor assesses hazards such as moving machinery, gas pockets, tidal current, ship movement, nearby traffic and electrical equipment. Control measures are agreed with the master and the engine room. If a hazard cannot be controlled, the dive does not start.
The supervisor stays in contact with the bridge or the master by radio or phone. The Diver speaks to the supervisor through the umbilical. This allows quick changes to the plan and quick action if something goes wrong. A dive flag is displayed, and nearby vessels are told by the agent or port control.
Each dive plan includes the location of the nearest medical facility and the arrangements for diving emergencies. The team carries first aid and oxygen equipment. Divers are medically examined and fit for work. We do not take risks with the people in the water.
Give us the ship's name, position and a short description of the problem. We confirm the team, the equipment and the estimated time on site. We respond as fast as team and equipment availability allow.
Q1. How many people are in an emergency Diver team?
Typically a supervisor, two working divers, a standby Diver, a surface tender and, where needed, a technician. That is 5 to 6 people.
Q2. What is the maximum depth for surface-supplied air diving?
Industry guidance sets it at 50 metres. Most ship work in port is much shallower, often under 20 metres.
Q3. What is the role of the standby Diver?
