Kenya’s fisheries sector relies heavily on well-maintained vessels to ensure safe and efficient operations, both for commercial fishers and research teams working on Lake Victoria, the Indian Ocean, and inland water bodies. Dry dock maintenance is a critical process where vessels are removed from the water for inspection, repair, and upkeep, helping to prevent costly breakdowns and ensuring compliance with safety regulations. Managing vessel positioning and docking during dry dock operations demands a high level of technical skill, careful planning, and strict adherence to safety standards. This chapter explores the essential procedures for inspecting lifting equipment and positioning vessels, equipping Fisheries Technology professionals with the knowledge to safeguard both assets and personnel.
2.1 Inspecting Lifting Equipment
Dry dock maintenance operations in Kenya’s fisheries sector frequently involve lifting vessels using specialized equipment such as cranes, straddle carriers, and mobile cradles. Proper inspection of this equipment is essential to avoid accidents, protect valuable fishing boats, and ensure compliance with occupational safety standards set by authorities like the Directorate of Occupational Safety and Health Services (DOSHS).
2.1.1 Types of Lifting Equipment Used in Fisheries Dry Docks
Different types of lifting equipment are used depending on vessel size, available facilities, and the specific maintenance tasks required. Understanding the features and functions of each is key to selecting and inspecting the right tool for the job.

Usage and Maintenance Considerations
- Routine Cleaning: Ensure all lifting equipment is free from debris, salt, and corrosive residues, especially after operations near the coast.
- Lubrication: All moving parts such as pulleys, cables, and joints must be lubricated according to the manufacturer’s schedule to prevent wear.
- Inspection of Load Chains and Slings: Check for frayed wires, deformation, or corrosion, which can compromise safety.
- Testing Safety Devices: Emergency stops and load limiters should be tested before every major lift.
- Record Keeping: Maintain a logbook of all inspections, repairs, and incidents for each piece of lifting equipment.
2.1.2 Inspection Procedures for Lifting Equipment
A systematic inspection routine is critical to detect faults before they become dangerous. Fisheries technicians in Kenya must ensure each step is documented and conducted with care.
Steps for Inspecting Lifting Equipment
- Visual Survey: Examine all surfaces for cracks, corrosion, or visible damage, especially in load-bearing areas.
- Check Mechanical Components: Inspect gears, winches, chains, and pulleys for alignment and smooth operation.
- Test Hydraulic and Electrical Systems: Activate all controls, checking for leaks, abnormal noises, or delayed responses.
- Inspect Safety Mechanisms: Ensure limit switches, brakes, and emergency shut-offs function correctly.
- Examine Slings and Hooks: Look for bending, excessive wear, or missing safety latches.
- Load Test (if required): Under supervision, conduct a controlled test using a load at or above the rated capacity to confirm structural integrity.
- Review Inspection Records: Cross-check current findings with previous logs to identify recurring issues or patterns.
2.1.3 Safety and Compliance Requirements
Kenyan fisheries professionals must adhere to national and international safety standards when using lifting equipment. This protects both workers and the vessels themselves, and ensures regulatory compliance during audits.
Key Safety and Compliance Aspects
- Certification: All lifting equipment must carry current certification from DOSHS or an accredited inspection body.
- Operator Training: Only trained and authorized personnel are permitted to operate cranes, hoists, or carriers.
- Load Limits: Never exceed the manufacturer’s specified load capacity, clearly marked on each device.
- Personal Protective Equipment (PPE): Operators and ground crew must wear helmets, gloves, and high-visibility vests.
- Emergency Procedures: Emergency stop buttons and clear evacuation routes must be accessible at all times.
- Signage and Barriers: Mark the operational area with warning signs and restrict access to authorized personnel.
- Incident Reporting: All accidents or near-misses must be reported and investigated according to organizational policy.
2.1.4 Common Issues Detected During Inspection and How to Address Them
Regular inspections often reveal recurring problems, especially in high-use fisheries facilities. Addressing these issues promptly minimizes downtime and prevents costly damage.
Typical Problems and Solutions
- Corrosion on Metal Surfaces: Clean affected areas, apply anti-corrosive paints, and schedule more frequent inspections during rainy or coastal seasons.
- Worn Hydraulic Hoses: Replace immediately to prevent leaks that can cause sudden equipment failure.
- Damaged Slings or Chains: Remove from service and replace with certified components.
- Misaligned Gears or Pulleys: Adjust and recalibrate before further use to prevent uneven loading.
- Non-functional Safety Switches: Repair or replace before any lifting operation is attempted.
- Unrecorded Maintenance: Update logs and retrain staff on the importance of thorough documentation.
Quality Check:
Before any vessel is lifted, confirm that all inspection steps have been completed, documented, and signed off by a qualified supervisor. This is a critical control point for safety and compliance.
