266At Taizhou ChangLong Shipbuilding Co., Ltd., navigating complex international shipbuilding regulations is a mission entrusted to our most seasoned experts. Meet Yang Zhigang, a 20-year veteran welder whose relentless pursuit of global certifications embodies our commitment to excellence. His journey reflects how we bridge China’s shipbuilding heritage with world-class standards.

When a European client demanded DNV-GL certified ice-class oil tankers in 2023, Yang faced a pivotal moment. "International projects require more than skill – they demand provable compliance," he recalls. His response? Mastering four critical certifications within 18 months:
CSWIP 3.1 Certified Welding Inspector (ISO 9712)
ABS Surveyor Accreditation for structural integrity validation
Lloyd’s Register NDT Level II (UT/RT/MT/PT)
IMO GHG Strategy Implementation Specialist
These credentials transformed him from a technician to a global standards guardian – and became our competitive edge.
Yang’s certification journey mirrors our company’s ethos:
Phase 1: 900-hour specialized training – From weld procedure qualification (WPQR) to finite element analysis (FEA) simulation
Phase 2: On-site validation – Implementing ASME IX standards on our 16,000DWT bulk carrier project
Phase 3: Knowledge transfer – Training 37 junior technicians in class-approved welding techniques
"Certifications aren’t paperwork – they’re DNA-level quality upgrades." – Yang Zhigang
Yang’s expertise now anchors our international deliveries:
These projects share one signature: "Approved by Yang" – a mark trusted from Oslo to Singapore.
Risk Mitigation – 0% NDT failure rates in ABS audits since 2024
Cost Efficiency – 30% faster certification cycles versus industry average
Future-Proofing – Early adoption of EU ETS maritime carbon rules
As shipowner Lars Johansen (Norway) confirms:
"ChangLong’s certified team turned complex IMO guidelines into buildable solutions."
Today, Yang leads our Global Standards Center – training engineers in:
ClassNK digital twin modeling
LNG bunkering system compliance
Ai-powered weld defect detection
His motto? "Every certificate is a bridge to client trust."
